俱舍論疏 9.9

9.9

論「欲中有量至四大洲等」，因明形量似當生處，兼明二界形量大小。異生、菩薩雖同欲界，而異生如小兒，菩薩如盛年等。

[On the] Śāstra's [words], "The size of intermediate existence in the desire realm... the four great continents, etc.": because of explaining that the shape and size resemble the place where one is to be born, it concurrently explains the size of shape in the two realms. Although ordinary beings and bodhisattvas are both in the desire realm, ordinary beings are like small children, while bodhisattvas are like those in the prime of life, etc.
